The Ana Sofia Agri-Gypsum Project (the “Project”) comprises two mining concessions totaling 50 hectares (ha) in size within a larger (approximately 600 ha) exploration permit area. The Project is well situated within a region where other small producers are currently extracting agricultural gypsum and selling to fertilizer distributors and farmers. An initial inferred gypsum resource for the Project was estimated (news releases – October 31; December 16, 2016), to comprise 1.47 million tonnes averaging 94.1% gypsum, using an 85% cut-off grade that is the minimum required gypsum content for commercial-quality agricultural gypsum products in Argentina.
